The initial authentication could be by username/password credentials, API keys or even tokens from another service.JWTs allow you to digitally sign information (referred to as claims) with a signature and can be verified at a later time with a secret signing key.The process by which an application confirms user identity is called authentication.Java 6 makes available 575 different time zone IDs for places around the world.It is recommended that Java Time zone IDs mentioned in the above table are used, instead of using three letter time zone abbreviations like “EST”, “PDT”, etc.JAXB 1.0 provided validation at unmarshal time and also enabled on-demand validation on a JAXB content tree.

JAXB 2.0 only allows validation at unmarshal and marshal time.

Section 2 is the payload, which contains the JWT’s claims, and Section 3 is the signature hash that can be used to verify the integrity of the token (if you have the secret key that was used to sign it).

Though Java can still recognise these for compatibility with Java 1.1, Usage of these abbreviations in JREs may produce unpredictable results.

Currently Java uses the “tz database” for listing of time zone related to a particular location.

Token authentication is a more modern approach, designed solve problems server-side session IDs can’t.
